Nappelon won Aqueduct's Grade 2 Comely Stakes in 1995 and the 1996 Owners' Day Dash Stakes at Delaware Park. Her first foal, the Broad Brush gelding Rawston, set a track record on the fair circuit in a career that spanned 35 starts, and Nappelon was the dam of another winner, King Cool, by Touch Gold.

But it was Nappelon's fifth foal, Ginger Punch, who made Nappelon's name. Sired by Awesome Again, Ginger Punch was voted champion older mare in 2007 after winning the Breeders' Cup Distaff, the Grade 1 Ruffian and Go For Wand Handicaps, and the Grade 2 First Flight.

Brown-Gambone purchased Nappelon from Frank Stronach's Adena Springs for $15,000 at the 2006 Keeneland January all-ages sale. The mare was in foal to Red Bullet at the time. Ginger Punch, then 3, made her first start that November.

Nappelon was entered in the 2009 Keeneland November mixed auction but was scratched.

As a racehorse, Nappelon won 17 of 70 career starts and earned $631,139.
